Fig. 12 is a side view of the mechanism for operating the drying-chain, a portion of the cams and levers for operating the gum- 7o ming mechanism also being shown in this figure. Fig. 13 is aplan of part of said drying-chain shaft, its operating-levers, ratchetwheel, pawl, and lock device, looking down, as indicated by the arrow in Fig. 12.

The object of my invention is to simplify the construction of an envelop-machine and to obtain as compact an arrangement of the parts as possible consistent with an easy and effective operation of said parts; and it consists of certain improvements in the construction and arrangement of those portions of said envelop-machine previously alluded to, and which will be hereinafter more fully set forth.

To enable those skilled in the art to which my invention appertains to better understand the nature and purpose thereof, I will now proceed to describe it more in detail. a

My invention relates more especially to improvements in the mechanism for elevating and lowering the gumming-heads, for grip ping and conveying the envelop-blanks to the folding-table and folders, for discharging the folded envelops from said folding-table 5 and folders and conveying the same to the drying-chain, and for discharging the finished envelope from said drying-chain and conveying them to the counting-box. The description will therefore be confined to said parts and so much of the old construction of an envelop-machine as will be necessary to make 2 ss goea clear my said improvements in connection therewith. V

The gumniin g of the back flaps is performed by means of two separate gum min g-heads B B, which are arranged diagonally to conform to the shape of the envelop, as is shown in Fig. 2, and mounted on the lower ends of vertical rods B B, fitted to slide in suitable stationary bearings 13 B Said rods are connected near their upper ends by a cross-bar B to which is pivoted the outer end of a link B, (see Fig. 6,) whose lower end is in turn pivoted by means of a transverse pin to the outer end of a cranlelevcr 15, secured at its opposite end to a horizontal transverse shaft 0, fitted to turn in stationary bearings O C in the upper ends of standards 0 C secured to main frame A. Said gumming-heads B B each consist of a holding-block B, the rubber or other elastic strip B fitted in a groove in said block and projecting a little below the bottom thereof, and the holding-plate B 7 fitted against the side of the block and clastie strip and fastened by means of screws B or otherwise to hold'said elastic strip in place, as is shown in Fig. 7.

The vertical rods B B are provided with fixed collars B B above the ends of the cross bar 13 which rest upon said cross-bar to sup port the rods and their gummingheads. Said rods are also each provided with the usual springs 13 B secured at their upper ends to the upper ends of the rods and at their lower ends to the ends of the cross-bar for exerting a downward yielding pressure upon said rods.

The shaft 0 is rocked in its hearings to intermittently raise and lower the gummingheads by a cam D on shaft E through the long connecting-rod D and crank-lever D the lower end of said connecting-lever D being provided with a friction-roll D which engages with the periphery of said cam D. The upper end of rod D is pivoted to the outer end of the crank-lever D and said crank-lever is secured to the outer end of transverse shaft 0. A longitudinal pressure is exerted upon the connecting-rod D toward its operating-cam to keep its friction-roll in engagement with the periphery of the earn, as is shown in Figs. 1 and 12, by means of a spiral spring D secured at one end to said connecting-rod and at its opposite end to frame A, and a yielding power is also obtained between the crank-lever D and the connecting-rod D by providing the outer end of said crank-lever with a lateral stud D, which fits in a suitable slot D formed in the end of the connecting-rod, to which stud one end of a spiral spring D is secured, while its other end is fastened to said connecting-rod, as is shown in Fig. 1 of the drawings. The object of said yielding power is to provide for any inequality in the pile of envelopblanks which may exist, and thus remove any injury to the operating parts that might occur if the parts were all made rigid. The

said edge is gripped between a plate F, se-

cured to carriage F, and a gripping-jaw F". pivoted at F to said carriage F, and which passes in between said gumming-heads B 13 in operation. The normal position of said gripper is when it'is down fiat against the plate F or upon the edge of an envelop-blank between the two, and it is thus held by torsionsprings F F, (see Figs. 5 and 9,) fitted over the pivot-spindle F. of the gripping-jaw l and adapted to exert a yielding rotary pressure thereon'to hold'said gripping-jaw down. as aforesaid, one end of each torsion-spring being fastened to said pivot-spindle F and their other ends being adapted to bear and hold against the carriage F, as is shown in Fig. 5. The gripper is opened at stated intervals to receive the edge of the envelopblank and to release the same by the forward and back reciprocating movements of carriage F"hetween the gummers and the folders, said reciprocating movements causing a friction-roll F, mounted on an arm extending down under the gripper, to engage with a balanced tilting lever F, mounted on an arm extending up from a projection on the main frame A, and with a similar balanced tilting lever F mounted on a projection on table I at the opposite end from said tilting lever F.

The carriage, it will be understood, is moved forward and back continuously with reeipro eating movements by the usual operating-lever H to convey the gummed envelop-blan ks to the table I under the plunger f. Assuming that a blank has been conveyed under said plun ger f by the carriage, its gripper, and fingers c c and said carriage is returning for the next blank with the gripper closed, as is shown in Fig. 9, when the friction-roll F comes in contact with the top inclined surface b of the tilting lever F said gripper is opened and passes over the edge of the blank, as is shown in Fig. 7, and immediately on passing by said tilting lever (by the continued forward movement of the carriage) again closes and grips the edge of the envelop between the same and the plate F. The movement or the carriage now reversing, the blank is drawn forward toward the plunger f over the usual guideways on bed or table I, and when the friction-roll engages with the other tilting lever F said gripper is again opened and re leases the blank. The carriage continuing to move forward carries the end of the gripper beyond the blank thus released, when it is closed again by the friction-roll F passing over in contact with and beyond the highest point of the tilting lever F Said carriage then reversing causes the gripper to be passed under said blank, leaving the latter on the guideway, the lever F tipping over to permit the free passage of the gripper and then swinging back into its original position, as in the former instance. The next gummed blank is then gripped, drawn forward into the same position and released, and at the same time that said blank is gripped the pusherfingers c 0 (one at each side of the carriage) engage with the edge of the blank previously conveyed forward, as is indicated in Fig. 5, and push it in advance of the following blank over onto the table I under the plunger f.

The gummed blanks having been forced down by the plunger f onto the folding-bed J and folded by the folders cZ, cl, (Z, and e in the usual way, they are each successively, as fast as folded, pushed from said folding-bed J and conveyed to the drying-chain K by mechanism constructed and arranged to operate as follows:

The folding-bed J is provided with a series of vertical openings, nine in this instance,.in which vertical pins 5 are fitted to work up and down, said pins being mounted in ahead g, fastened to the upper end of a vertical rod g which is pivoted at its bottom end to a horizontal lever h, in turn pivoted at the opposite end from rod g to a horizontal transverse shaft 72, or other stationary bearing. The free end of said lever h is raised by a earn 1' on the horizontal transverse rotary shaft E and drops, when the cam-pressure is released, by force of gravity. A roll j may be mounted upon the end of lever 71 for the cam to impinge against to reduce friction of the parts. The purpose of said vertical fingers g and their operating mechanism is to raise the envelops 71;, after they have been folded, above- 3 the folding-bed J, as is illustrated in Fig. 4,

to bring them in line with the forked pushers Z Z, so that the latter may push them forward edgewise over the front folder 6 far enough for them to tip over and slide down the guideway L into the drying-chain K, as is also indicated in Fig. 4. The vertical rod it will be understood, is operated with intermittent vertical movements to raise and lower the pins 9 in unison with the folding operationthat is, they are allowed to drop so that their upper ends will come at or below the level of the top of the folding-table, before the envelop-blank is de posited thereon,and moved up to raise the envelop, immediately after it is folded, preparatory to being pushed forward by the forked pushers Z Z, as previously described.

To facilitate the downward slide movements of the envelops when pushed forward as aforesaid by the forked pnshersZ Z, the tops of the pins g, upon which said envelops rest, are preferably arranged at an incline to 'the top of the folding-table by varying the lengths thereof to obtain a downward incline toward the front folder, as is shown in Fig. at. Therefore, since said forked pushers are moved forward with quick movements, when they strike the back edges of the envelops the latter are carried forward also with a quick movement, and the impetus imparted thereto causes them to be carried and tipped over from the front folder and foldingbed into the guideway L, down which they slide with the front flap underneath, or in a reversed position to that which they occupied when resting on the tops of the pins g. Said guideway consists of two angle-plates, one at each side of the envelops, with a space between them, and they slant inward toward the center of the machine, so that their inner ends, where the envelops pass therefrom into the dryingchain, come about under the center of the folding-table. By this arrangement it is obvious that I am enabled to greatlyeconomize in space in the construction of the machine over the usual constructions adopted in other machines. I am also enabled to dispense with the close chute usually employed for guiding the envelops to the drying-chain, in this instance only the angle-plates at each side of the en velops being necessary to properly guide the envelops to said drying-chain.

The forked pushers Z Z are moved horizontally and longitudinally by a cam n on the same shaft E that the cam i is secured to and by the spiral springs s 8', said springs causing said forked pushers to be moved forward toward the envelops to push them forward and the cam causing them to be moved back again preparatory to pushing the next envelop forward, connection between cam i and the forked pushers being made through the friction-r0110, connecting-rod p, pivot-pin p, crank-lever q, horizontal transverse rockshaft q, and crank-levers g The roll 0 is mounted on a stud 0 on the lower end of connectin g-rod p, and the periphery of cam n engages therewith to impart the desired movements to the rod 13 and parts connected therewith. Spring 13 connects with the end of crank-lever q, and s with crank-lever (1 also on shaft q, the other ends of both springs beingin practice secured to some stationary part of the machine. If desired, the cranklever q and its spring 3' may be dispensed with.

The rod p is pivoted to shaftE by its lower end being made fork-shaped and fitted over said shaft, as is indicated by dotted lines in Fig. 4, and at its upper end to the pin 19. The outer end of crank-lever q is pivoted to rod 1) and its inner end is ,secured to rockshaft q. The crank-levers Q2 g are likewise secured at their bottom ends to said rockshaft q and are pivoted at their upper ends to the forked pushers Z Zat g (f. In order that said forked pushers Z Z shall be moved horizontally in line with the envelops resting on the supporting-fingers g, they are double pivoted at their base ends not only to the le vers g g at g qfibut also at r 4" to the levers r 7'. Said levers *r r are attached at their lower ends to a horizontal transverse shaft r each pair of levers 1 and r being arranged substantially parallel to each other, as is shown in Fig. 4-, when the parts are fitted for operation.

By the above construction and arrangement it is obvious that when the upper ends of levers g g are moved forward and back by the action of springs s s and cam a both sets of levers g g and r r moving together cause the forked pressers to be moved for- Ward and back always in the same horizontal line with the envelops. Said envelops after having been carried around in the dryingchain to be dried, as usual, are pushed from said drying-chain and conveyed to and discharged into the counting-box M in the following manner:

Two forked pushers i i, similar to but longer than the forked pushers Z Z, previously described, are pivoted at their base ends to the upper ends of the crank-levers '6 t, which are in turn secured at their lower ends to the horizontal transverse rock-sl1aft t To said shaft is also secured the upper end of a cra nklever i to whose lower end is pivoted one end of a connecting-rod 25 which is fork-shaped at its opposite end and pivoted to the same shaft it that the lever h is pivoted to. Said connecting-rod t is provided with a friction roll i with which the periphery of a cam 25 on shaft h engages, similar to the rod, roll, and cam employed for operating the other forked pushers Z Z, previously described. The action of said cam i is to move the forked pushers t 6 forward. They are moved back again when said cam-pressure is released by a spring 8 attached to the crank-lever i The forward ends of the forked pushers it rest on horizontal transverse supportingstuds 25 t and said forked pushers are beveled on their under sides, as is indicated at i in Fig. 4:, so that when they are moved forward over said studs t their forward ends will be gradually elevated slightly to conform to the inclination of the blade in the drying-chain coming at that point and with the incline at which the envelops should be pushed forward for the grippers N N to grasp the same and draw them forward over the counting-box M.

The mechanism for gripping the envelops, conveying them forward, as aforesaid, and depositing them in the counting-box is constructed and arranged to operate as follows: Said mechanism is operated from the same lever H that is connected with the carriage F for conveying. the envelop-blanks to the folders. To said lever H is pivoted one end of a link it, (see Fig. 1,) Whose opposite end is pivoted to the bottom end of a crank-lever it, secured at its upper end to a horizontal transverse rock-shaft n fitted to turn in suitable bearings on the guideway L. To said rook-shaft n are also secured the upper ends of crank-levers u a having the gripping 1evices N N mounted on their lower ends. Said devices are moved forward and back toward and from the drying-chain by the rocking movements of the shaft M, which oscillating movements also cause the grippers to he opened and closed to grip and release the envelops, being closed immediately after the edges of the envelops are received therein and remaining closed until the envelop is conveyed to the proper point over the counting box, when they are opened and allow the same to drop into said counting-box. The upper jaws o o of said gripping devices are formed upon or rigidly secured to the levers w 4. while the bottom jaws o 2; thereof are secured to a horizontal transverse shaft 12 fitted to rock in the lower ends of the levers 'LLS a "30 one end of said rock-shaft is secured one end of a crank-lever o (see Figs. at and 10, to Whose opposite end is pivoted the end of a lever v fitted to swing and also to move longitudinally on a pivot-stud 12 at the opposite end thereof, mounted in a stationary standard 0, said lever o being slotted longitudinally, as is shown at 'v in Figs. at and 10, to admit of the aforesaid longitudinal movements thereof. The opening r in the upper end of the standard 0 to receive the pivot-stud o is also made oblong in shape or slotted in alinement with the slot o to admit of the lateral ad ustment of said pivot-stud By thus slotting the lever '0 it is permitted to move the length of its slot with the levers it a without moving the crank-levers o and the bottom jaws 'v 1:, but when said lever 1 strikes at one end or the other of its slot 2; against the stud 0 said jaws are opened or closed, according to which end comes in contact with said stud. and remain thus opened or closed until the lever strikes the stud at the opposite end of its slot, when the action is reversed-as, for example, assuming that the jaws are closed and moving forward with an envelop to convey it over the counting-box, they are opened again upon arriving at the proper point to release said envelop to allow it to drop into said counting-box, as is indicated by dotted lines in Fig. 4, by the lever o striking against the pivot-stud 11 at the inner end 12 of its slot 12 said operation causing the crank-lever r to be swung around to rock the shaft t and swing down thebottom jaws v '1}, by the continued forward movement of the main cranklevers U 103, in which position they are held by a small spring-spindle o fitted in a suitable transverse opening in the lower end of one of said crank-levers u and adapted to bear endwise against the side of the small crank-lever 11 as shown in Fig. 11. hen the crank-levers 16 7.6 return toward the center of the machine to get another envelop and the lever 21 comes against stud v at the opposite or outer end of slot '0 the cranklever o is moved in the opposite direction and the bottom jaws thereby closed to grip the envelop, the parts being so adjusted as to thus close the gripper just after the envelop has been pushed from the drying-chain in between the jaws of said gripper. The bottom jaws are held closed against the upper ones '1; with suflicieut power to prevent the envelop from being withdrawn in conveyin g the same to the counting-box by a torsion or other suitable spring r adapted to exert said pressure, and yet insufficient to move the crank-lever '0 against the holding spring-spindle o hen said lever 22 is swung in either direction to its extreme limit to open or close the gripper N, the springspindle o occupies a position to one side or the other of said cranlelever, as is indicated by dotted lines in Fig. 10, with its head bearing against the upper or under edge of the lever to better hold the same from a swinging movement, except when forcibly swung around by contact of lever UL with the pivot-stud o as previously described. To facilitate the above operation, said head of the springspindle 1: may be slightly rounded, as is shown in Fig. 11.

If desired, the grippers N N may be provided with. curved guards N, curving upward and inward therefrom toward the guideway L to prevent the envelops from accidentally passing over the grippers when pushed forward from the dryingchain; but as said guards are not an essential feature I reserve the right to use the same or not, as preferred.

lVhen the envclops are released from the grippers N N, they drop into and slide down the guideway P into the counting-box, being guided at the front side in passing down by the guide-plate P. (Shown in Fig. 4. As said counting-box does not constitute a part of my invention it will be unnecessary to de-' scribe the same in detail.

The mechanism for operating the dryingchain with the usual intermittent movements (illustrated by Fig. 12 of the drawings) consists of the rock-lever S, mounted on the drying-chain shaft Q and operated by a cam S, friction-roll S and connecting-rod Upon said shaft Q are also mounted and fitted to turn therewith the ratchet-wheels Q R, which engage, respectively, with the pawls Q and R, the pawl Q being pivoted to the outer end of the rock-lever S and the pawl R to frame A at B The pawl Q and the operating mechanism connected therewith turn the ratchetwheel Q and through the shaft Q, the drying-chain with the usual intermittent move ments, and the pawl R serves by its engagement with ratchet-wheel R to lock said parts from any forward. movement which might occur from the momentum imparted thereto by the pawl Q and other parts in turning the same. lVhen the outer end of rock-lever S is elevated to carry forward pawl Q, so as to engage with one of the notches of its ratchetwheel, a pin on said leverstrikes and raises the pawl R above the notches of its ratchetwheel and is not again lowered sufficiently to engage therewith until just prior to the pawl Q leaving the notch in its ratchet-wheel. By said time the supporting-pin R has been lowered the proper distance to permit said pawl R to drop down in front of one of the notches 'of ratchet-wheel R, and thereby holds the parts locked until the pin R forces the same up again in the operation of moving the pawl Q forward to engage with the next notch of its ratchet-wheel to again turn the dryingchain.

13 y the foregoing construction and arrangement of the various improved parts of an envelopunachine it will at once be apparent to those skilled in the art to which my invention appertains that great compactness is obtained in the disposition of the operating parts without affecting the utility thereof, and by the application of said invent-ion to practice I am enabled to produce en velops of a superior quality and with great rapidity.
